Custom settings activeThe tool finds the highest quality that still meets the target size, and scales down only if needed. Images already under the limit are left unchanged.

When you need 500KB
Online stores, website uploads, and email-friendly photos often sit comfortably near 500KB.
If you cannot hit the target
WebP or JPEG at moderate quality usually hits 500KB easily after a mild resize. Keep PNG for logos with transparency.
Hitting 500KB without uploading
| Compared to | Compress Locally (this site) | Typical upload tools |
|---|---|---|
| Size goal | Aim for about 500KB on your device | Upload first, hope the result fits |
| Privacy | ID photos and form uploads stay local | Sensitive uploads go to a third party |
| If still too large | Lower max width, switch to JPEG/WebP, retry | Often a single opaque “compress” button |
| Batch & limits | Batch several files; bound by device memory, not a free-plan quota | Daily caps and file-count limits are common |
Frequently asked questions
Is 500KB OK for a website?
Smaller images help pages load faster. 500KB is a reasonable size for many blog and product photos; go lower for thumbnails and hero images above the fold.
Do you store my images?
No. Processing is local only — your files stay in the browser and are never uploaded. See the Privacy page for full details.
Will every file land exactly at 500KB?
The tool aims close to 500KB by adjusting quality and dimensions. Simple graphics may finish well under; detailed photos may need a mild resize to hit the cap.
Result looks soft or still too large — what now?
Open Compare on that result for a before/after preview. Use Adjust to re-run just that image with different quality, target size, or max width.
